LibreOffice 4.2, the free and open-source office suite, is now available with enhanced performance, interoperability, and improved integration with Microsoft Windows.

Here are some of the new features announced:
LibreOffice 4.2: main new features
Calc has been completely revamped to deliver better results with large amounts of data, particularly when calculating cell values and importing large complex tables.
This improvement is useful for users who work with spreadsheets containing many rows, formulas or imported tables. Calc is designed to handle these operations more efficiently in LibreOffice 4.2, especially when working with large amounts of data.
Interoperability with Microsoft OOXML, especially for DOCX, as well as RTF inheritance, has also been significantly improved. Additionally, new import filters for AbiWord documents and Apple Keynote presentations have been added. Furthermore, thanks to better integration with Windows 7 and 8, thumbnails of open documents are now grouped by application, and the list of recent documents is displayed in the taskbar.
These improvements help users open, edit and exchange documents in several common formats. The improved support for Microsoft OOXML, DOCX and RTF is especially relevant for users who need to collaborate with people using different office software.
LibreOffice 4.2 introduces a new startup screen, featuring a clean layout that allows for better use of available space - even on smaller screens - and displays a preview of the most recently used documents.
The startup screen gives quick access to recent documents. Its clean layout is also designed to make better use of the available screen area, including on smaller displays.
On the mobile front, LibreOffice now supports a remote control Impress for iOS – this functionality was already available for controlling Impress remotely with an Android device. This allows users to manage their visual presentations on a laptop using the screen of an iPhone or iPad. The application is currently under review by Apple and will be announced as soon as it becomes available on the iTunes Store.
With Impress remote control, presentations can be managed from a mobile device while the slideshow runs on a laptop. In LibreOffice 4.2, this feature is mentioned for iOS, while remote control with an Android device was already available.
